Description of key information
The Key study with the read across substance aluminium sulfate as one of the components of
aluminium potassium bis sulphate from Scott et al. gave an estimated NOEC-7d for Ceriodaphnia dubia
for aluminium potassium bis sulphate of 4450 mg/L total Al and 1.50-2.20 mg/L aqueous Al.
The supporting study from Lamb et al. also with read across substance aluminium sulfate gave
an estimated NOEC-55d for Tanytarsus dissimilis of 3 mg/L aluminium potassium bis sulphate.
Resulting from the 2 Read across long-term studies the calculated NOEC for freshwater invertebrates
is 1.5-3.0 mg /L as aqueous Al of aluminium potassium bis sulphate = 14.36 - 28.71 mg/L
aluminium potassium bis sulphate.
Resulting mean NOEC value: 21.54 mg/L aluminium potassium bis sulphate.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
